Answer:
The probability of selecting the given event = [tex]\frac{25}{52}[/tex]
Step-by-step explanation:
A card is drawn at random from a standard 52-card deck.
We have to find the probability of selecting an odd numbered card(3,5,7,9) or spade or both.For this we have to find the number of favourable cases.
Favorable cases = 13 (all the spades) + 12(4 odd numbered cards from each of the remaining 3 )
= 25
Final probability = [tex]\frac{number of favourable cases}{total number of cases}[/tex]
= [tex]\frac{25}{52}[/tex]
Hence the probability = [tex]\frac{25}{52}[/tex]
